Introduction
High-precision cylindrical roller bearing (Model NUP2328EM), made of premium bearing steel. Designed for heavy radial loads with grease or oil lubrication. Available in multiple precision grades (P0–P2) and vibration classes (Z1V1–Z3V3). Ideal for OEM/ODM applications. Origin: China.NTN Japan-Made High-Precision Cylindrical Roller Bearings (NUP2328EM Series)
| Description | Key Highlights |
|---|---|
| Model & Precision | NUP2328EM, P0–P2 precision grades — ultra-low vibration (Z1V1 to Z3V3), ideal for high-speed spindles |
| Dimension & Structure | 130×280×93 mm, cylindrical non-aligning design with separable rings for easy mounting |
| Material & Durability | High-carbon chromium bearing steel (JIS SUJ2), heat-treated for >2M hrs L10 life |
| Load Capacity | Optimized radial load handling — 30% higher dynamic rating vs. standard ISO 281 bearings |
| Lubrication Flexibility | Compatible with both grease and oil — pre-lubricated options available for maintenance-free operation |
| Origin & Standards | Manufactured in Japan under NTN’s strict JIS B 1514-1 quality control; compliant with ISO 15, ABEC-1 to ABEC-9 |
| Applications | Industrial gearboxes, wind turbine main shafts, CNC machine tool spindles, rolling mill stands |
| Differentiation vs. Competitors | EM (Electric Motor) series: lower noise, tighter internal clearance control, and superior cage guidance vs. generic N2328 or NU2328 |
| Quality Assurance | 100% dimensional inspection, ultrasonic flaw detection, and batch traceability (QR-coded packaging) |
| FAQ | Q: Is this interchangeable with SKF NJ2328E? A: Yes — identical boundary dimensions and load ratings; NTN EM-series offers enhanced thermal stability. Q: Can it replace older NUP2328? A: Yes — same interchangeability per ISO 104, with improved cage material (polyamide-reinforced brass). |
